A few weeks ago I sent a post and talked with students about demonstrating a simple science experiment in front of the class, and giving an explanation of how it works.

Students will give their presentations the weeks of March 9th and 16th, (the 2 weeks before spring break). I gave a 2 week time frame because I know many students are sick or go out of town this time of year. If your student is prepared, please have them bring their experiment next week (week of 3/9). If they need another week to prepare, they may present the following week (week of 3/16). If you cannot make either of these dates, you may arrange another day sometime later in the semester.

 

The experiment presentation/explanation should last 3-5 minutes, and can demonstrate any scientific topic. You can show a chemical reaction or optical illusion, or share the results of a longer-term experiment you've been doing at home. Past demonstrations include: making a lemon battery, baking soda and vinegar volcanos, explaining why a straw in a glass of water looks bent (refraction),  growing plants in different soil and water conditions, and lots of mentos and Coke.  It can be as simple as rubbing your feet on the floor to produce static electricity. The important thing is that the student can give a detailed explanation of how it works in their own words, not reading from a card. The explanation should last about 1 minute and they should be prepared to answer questions to the best of their ability.

 

If the demonstration has to be done outdoors, or if it involves fire, you may make a video and I will share it in class. The student will still need to give an explanation to the class in person.

Let me know if there are any questions!
